Past – Present – Future

A thought arised from a Carrie Bradshaw quote, "can you get to your future if your past is present?" (helllooooo Sex n The City fans… correct me if I’m wrong…)

In
a world moving so quickly that you already start chatting up another person before you even finish with the first one, we have an inclination
to classify people by the bad things they did – liars, cheaters, or
whatever – yet we leave it there after we’ve moved on. We come to
believe and accept that a past liar will always lie.

Is it fair
that people are judged by what they did in the past? More importantly,
is it fair if people judge you by your past behaviour?
